I want the chart to be much larger regardless of the values. Currently, the chart is the height in the picture and it does not change. This is the complete configuration for the chart I currently have. Is it possible for the chart to have more height regardless of the dataset values?
const KYCctx = document.getElementById('kycChart').getContext('2d');
const KYCChart = new Chart(KYCctx, {
type: 'bar',
data: {

return chart.data.labels.map(
(label, index) => ({
text: label,
fillStyle: chart.data.datasets[0].backgroundColor[index],
strokeStyle: chart.data.datasets[0].backgroundColor[index],
}
)
)
}
}

You could explicitly define the height on the canvas.
<canvas id="kycChart" height="400"></canvas>
const KYCChart = new Chart('kycChart', {

],
borderColor: [
' rgba(203, 55, 55, 1)',
'rgba(34, 195, 107, 1)',
'rgba(255, 171, 45, 1)'

borderWidth: 1
}]
},
options: {
scales: {
y: {
beginAtZero: true,

return chart.data.labels.map(
(label, index) => ({

fillStyle: chart.data.datasets[0].backgroundColor[index],
strokeStyle: chart.data.datasets[0].backgroundColor[index],
})
)
}
}
},
title: {
display: true,
align: "start",
color: "#ffff",

I looked for a lot of things to add a feature to my chart but

Given my chartJS config below
var ctx = document.getElementById('myChart').getContext('2d');
Chart.defaults.global.defaultFontColor = 'rgba(255, 255, 255, 1)';

I need to get something as close as the following
Using Quickchart API, I am submitting the config through the URL, but I am having trouble setting the labels color? options:{legend:{labels:{fontColor: 'white'}},

My work
Expected Output
I'm having a problem on how to set the labels text align to left. What I want to do is I want my label same with the next picture but I don't know where in Options:{ settings for text align. Is there anyone can help me how to fix it? I can't find any on the https://www.chartjs.org/docs/latest/configuration/legend.html. Thank you in advance.
The yAxis.ticks labels can be left aligned by defining mirror: true combined with adding some padding.
yAxes: [{
ticks: {
mirror: true,
padding: 220
},
To make the labels visible on the chart area, the same padding needs to be defined left of the chart layout.
layout: {
padding: {
left: 220
}
},
Please have a look at your changed code below.
new Chart('myChart', {
type: 'horizontalBar',

You can control labels alignment by using crossAlignment option on the tick configuration. There are three possible values: "near", "center", and "far".
In your case, you will just use near
options: {
...
scales: {
y: {
ticks: {
crossAlign: "far",
},
},
},
}
I want to do an horizontal bar with 2 yaxes, Where a bar can have a positive or negative value and positive side has a yaxis and the negative side has other yaxis like the image
This is my code JSFiddle.
I can't change the names of the second yaxes
I add arrays with the same values because i would want two yaxes, It is not necessary to use "chart.js" if you knows other library where i can it use, please tell me
